GENERAL DESCRIPTION
The W91350N series are tone/pluse switchable telephone dialers with thirteen memories, hold
function, and a handfree dialing control circuit. Fabricated using CMOS technology, the W91350N series
offer good performance in low-voltage and low-power applications.
FEATURES
DTMF/pulse switchable dialer
Two by 32-digit redial memory and save memory
Three by 16-digit one-touch direct repertory memory
Ten by 16-digit two-touch direct repertory memory
Cascaded dialing allowed, with unlimited dialing length
Pulse-to-tone (*/T) keypad for long distance call operation
Uses 5
Easy operation with redial, flash, pause, and */T keypads
Pause, P T (pulse-to-tone) can be stored as a digit in memory
Dialing rate (10 ppS or 20 ppS) is selectable by bonding option
On-hook debounce time: 150 msec.
Minimum tone output duration: 93 msec. (W91354AN: 87 mS)
Minimum intertone pause: 93 msec. (W91354AN: 87 mS)
Flash break time (73, 100, 300, 600 msec) selectable by keypad; pause time is 1.0 sec.
Make/break ratio (40:60 or 33.3:66.7) selectable by MODE pin
On-chip power-on reset
Uses 3.579545 MHz crystal or ceramic resonator
Packaged in 18 or 20-pin plastic DIP
The different dialers in the W91350N series are shown in the following table:
Note: The W91354AN is for use in France only. The pause time is not added in pulse-to-tone function mode.
